Port scanning attacks!

Since the other thread is resolved I have come accross another issue I am having troubles with!

So it started back about a month ago when a computer on my network started port scanning my PC, Fair enough I went to the computer that was port scanning and located the virus and deleted it. Issue went away for about a month but has come back and wont leave my internet and my computer alone!
Only way I know is that it shows up on my NOD32 Firewall saying theres a port scanning attack blocked coming from the other computer. I have run AntiVir & NOD32 Virus scanner on the infected PC but neither find and delete the virus so Is there any scanner that specialises in finding the source of the problems and removing it? I'm still pretty stumped that two pretty decent AV's couldn't pick it up... What should I do?
Oh and everytime it attempts to port scan my PC it interferes with my latency in game :(

On the scanning machine you may try using
Code:
netstat -bn

and locate the target IP and you will see the process that is causing the issue bellow the found connection
 
Maybe I should run Hijack this? I've heard it to be a good program to locate processes running..

The log presented a few uTorrent lines, one opera line & a strange line stating it had established a connection to my network IP but "Could not obtain ownership information" -,-

EDIT: I Also see
Windows Sockets initialization failed: 5
With a few random IP's there.

Reboot both PC's, simple as I guess.

That won't help since it's most likely a virus of some sort and will start at boot

If you post the output of the command I told you to run, I might be able to help you locate the process. Also try booting the attacker in safe mode to see if the attack persists
 
The PC Is a media centre computer so I can't afford just to leave it in safe mode for a long peroid of time..

As I say this my PC is still blocking port scan attacks, Happening a couple of times per hour and slowing down my connection each time it happens.

EDIT: Oh and the infected PC Always uses the port 5355 to port scan attack my PC if that helps.

Did a bit of research and you might be infected with some form of trojan backdoor, apparently Kaspersky might be able to clean it.

Have you tried testing in safe mode if the scanner starts?
 
Will the kaspersky online virus scanner be good enough to scan the infected PC?
http://www.kaspersky.com/virusscanner

If so i'll scan the PC with that tomorrow... And if that doesn't work i'll try in safe mode.

EDIT: Should I just download a trial version of it to scan? Online scan doesn't seem to support removal of any malware detected.
